It would be a herculean effort to change Citizens United. It was a Supreme Court decision. So it would require either swapping out several justices or convincing a large number of Republicans to join in on a legislative change. The Democrats had both chambers and the White House since then and either it was still out of reach or just not a priority.

It got pased once, it can get past again.

You're talking like it can never happen no matter what, but since it has happened, it could happen again.

The next Congress can have a very different vote makeup than the current one we have.

I’ve also heard rumors that Net Neutrality is coming back but it hasn’t happened yet.

I don't think the new commissioner has been sworn in yet, but it's supposed to happen soon.

We handle it at the regulatory level rather than the legislative level. So even if Biden does manage to get it re-instated, it will likely disappear again with the next Republican president.

Maybe, Maybe not. A lot of laws that are controversial on party lines get established and stay that way, welfare, social security, etc.

Policies like that need to be consistent or they don’t really work. Otherwise we’re essentially telling large media companies, “You can totally mess with competitors access capabilities but only every other presidential term.” That give them plenty of time to bankrupt competitors.

You're assuming a cyclical cycle between the two parties being in power, which is not always true.

Also as generations come and go, things do change and do settle down. It just takes time sometimes, again generationally level time.
